🚗⚠️ Got a on my Renault – driver seatbelt pretensioner resistance too high.

⚠️ Always disconnect the battery for 15+ minutes before touching any SRS component! dtc b123a renault

Quick check: loose yellow plug under the seat again! 🤦‍♂️ Unplug, clean, reconnect, clear code… and it’s gone. Worth checking before buying parts!

🚨 🚨

Always check the connector first before replacing the pretensioner. Very common on Renaults with adjustable seats. ⚠️ Always disconnect the battery for 15+ minutes

1️⃣ Check & clean the yellow connector under the driver’s seat. 2️⃣ Inspect wires for breaks or pinches. 3️⃣ Reset the fault with a diagnostic tool (OBD scanner with SRS support). 4️⃣ If code returns, test pretensioner resistance (2–3 ohms is normal). 5️⃣ Replace pretensioner if out of spec.
